Benefits of technology
[0015] Therefore, the present invention has been made in view of the above problems, and it is an object of the present invention to provide an apparatus for summing capacities of outdoor units in a multiple air conditioner that is capable of automatically calculating and storing the total capacity of the outdoor units when the multiple air conditioner is operated with self-capacities stored in the outdoor units to operate the air conditioner, thereby accomplishing accurate calculation of the total capacity of the outdoor units, and therefore improving operational reliability of the air conditioner.
[0016] It is another object of the present invention to provide a method of summing capacities of outdoor units in a multiple air conditioner that is capable of automatically calculating and storing the total capacity of the outdoor units when the multiple air conditioner is operated with self-capacities stored in the outdoor units to operate the air conditioner, thereby accomplishing accurate calculation of the total capacity of the outdoor units, and therefore improving operational reliability of the air conditioner.
[0025] According to the present invention, the self-capacity is stored in each of the outdoor units, and the total capacity of the outdoor units is automatically calculated and stored through communication between the outdoor units. As a result, the possibility of incorrect input of the capacities of the outdoor units is eliminated, and therefore, more accurate control of the multiple air conditioner is accomplished. Furthermore, it is not necessary for an engineer or a user to directly input the capacities of the outdoor units, and therefore, user convenience is improved.
[0026] In addition, when additional outdoor units are to be installed, the capacities of the additional outdoor units are automatically added to the capacities of the existing outdoor units, and the total capacity of the outdoor units is calculated and stored so long as the added outdoor units are connected to the circuit of the air conditioner system. Consequently, addition or removal of the outdoor units is easily and conveniently accomplished.
Problems solved by technology
According to the method of summing the capacities of the outdoor units in the conventional multiple air conditioner, however, incorrect sum of capacities may be inputted due to errors of an engineer who initially installs the conventional multiple air conditioner.
In this case, control is not accurately performed.

Embodiment Construction
[0031] Now, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
[0032]FIG. 2 is a block diagram showing an apparatus for summing capacities of outdoor units in a multiple air conditioner according to the present invention.
[0033] As shown in FIG. 2, the multiple air conditioner comprises a plurality of indoor units 50 and a plurality of outdoor units 60, which are connected to one another to perform a cooling or heating operation according to a cooling cycle.
[0034] A self-capacity storage device 70 is mounted in each of outdoor units 62, 63, and 65, among the plurality of outdoor units 60, for storing self-capacity of each of the outdoor units 62, 63, and 65 and outputting the self-capacity of each of the outdoor units 62, 63, and 65 when necessary.
[0035] One of the outdoor units 60 is classified as a main outdoor unit 61, and other outdoor units 62, 63, and 65 are classified as subsidiary outdoor units. The self-...
